3 Claims.

This invention relates. to window raisers for automotive vehicles. and has for an object to provide a device of. this character which may be operated with minimum manual effort to move the window pane to any desired adjusted position.

A further object is to provide a device of this character which will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scopeof the appended claims without departing from the spirit orsacrificing any of the advantages of the invention.

In the accompanying drawings forming a part of this specification:

Figure l is an elevation looking to the inside of a motor vehicle door equipped with a window raiser constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view of the window raiser with parts in elevation.

Figure 3 is a detail sectional view taken on the line 33 of Figure 1.

Figure 4 is a View similar to Figure 3, but showing the dog depressed.

Figure 5 is a rear elevation of the window raiser shown in Figure 1.

Figure 6 is a detail plan View showing the position of the parts when the barrel is rotated in one direction.

Figure 7 is a detail plan View showing the parts when the barrel is rotated. in the opposite direction.

Figure 8 is a detail perspective view of the hub and operating. shaft..

Figure 9 is a detail perspective view barrel.

Referring now to the drawings in which like characters of reference designate similar parts in the various views, In designates a motor vehicle door and H the glass window pane thereof. For controlling the window pane, the window raiser forming the subject matter of this invention comprises a housing formed of two shells l2 and I3, which are secured together by bolts M to house the working parts, these bolts being engaged through the inner wall l5 of the door to secure the housing to the door. One of the bolts is also engaged through the short leg of of the a U-shaped. frame IS, the long. leg of the frame being, spaced from the housing and having riveted thereto, as shown at IT, the flattened intermediate portion of an elongated leaf spring l8 for counter-balancing the weight of the. window pane, and which will be later described.

On operating shaft is is rotatably mounted in an axial tubular bearing 20 which is integral with the shell IS. The shaft is equipped with a crank handle 2| which may project through a slot 22 in the upholstery 23, if desired. As best shown in Figure 8, the shaft I!) has formed integral therewith adisk hub 24, and a split sleeve 25, comprising two companion arcuate sections 26, is formed integral with the hub. One of the sections is'provided with anotch 21.

A cylindrical barrel 28' is received between the arcuate sections 26 and is provided at diametrically opposite points with longitudinal ribs 29 which are received in the spaces 38 between the arcuate sections. The barrel is provided with a collar 3! which is confined against a stop shoulder- 32 formed in the shell l2. Beyond the collar the barrel is provided with a cylindrical extension 33 which fits in a tubular bearing 34 formed integral with the shell i2, and beyond the bearing, the extension is flattened, as shown at 35, to be received in an opening formed intermediate the ends of an operating lever When the barrel is turned, the lever will be turned to raise or lower the window pane, as will presently be described.

A dog 3?, best shown in Figures 3 and 4, is slidably mounted in a radial opening 38 formed in the barrel. A helical spring 39' is seated in the opening beneath the dog and tends constantly to hold the dog moved upward into engagement with ratchet teeth ii], formed on the inner periphery of the shell It. The dog is provided with a bevelled end M. and isv cut away near the; bevelled end to provide shouiders 42 which are also bevelled at! theout'er ends.

A helical spring 43 is. sleeved on the shaft f9 and is secured at the ends in the shell. I 3 and in the disk hub 24. The spring normally holds the hub and extensions 28 in such position that the notch 21 is disposed laterally of the dog 31 so that the projecting portions 4 of the arcuate section on each side of the notch cannot engage over the shoulders 42 of the dog until the window is to be lowered.

The beforementioned leaf spring I8 is provided on each side of the lever 36 with a convolution 45 and the free ends of the spring are engaged in notches 46 in the lever on opposite sides of the shaft is. with a pin The upper end of the lever is provided H which engages in a longitudinal slot 48 formed in the lower frame member 49 of the window pane H The spring is under tension, so that when the parts are in normal position, and during operation of the device, the weight of the window pane H is approximately counter-balanced so that manual exertion in operating the device is reduced to a minimum.

When the window is closed, the dog 31 will be engaged back of a ratchet tooth ii), as shown in Figure 3. When the window is'to be lowered, crank handle 2i is turned counter-clockwise, as

best shown in Figure 4, and during the initial stages of rotation the projecting arcuate sections will pass over the shoulders 42 on the dog 37 and depress the dog and finally lodge against the rib 29 in back of the'dog so that continued rotation of the crank handle will turn the barrel 58, with resultant swinging of the upper end of the lever 35 downwardly to lower the window to any desired position, either partly open or fully open. When the crank handle is released, the spring 23 returns the hub 26 and arcuate sections 26 to normal position so that the dog is freed and is immediately moved by its controlling spring 39 to engage back of a tooth-in the shell I 2 and hold the window in adjusted open position.

When the window is to be raised, the crank handle is turned in a clockwise direction, as indicated in Figure 3, and in this position of the parts the rib 29 of the barrel by engaging the dog 31 rotates the barrel, the dog meanwhile moving over the ratchet teeth with ratchet action while the barrel is rotated to rock the lever 35 and raise the window to any desired position, either fully closed or partly closed. When the crank handle is released, the controlling spring lid of the dog disposes the dog in back of one of the ratchet teeth to hold the Window in adjusted closed position.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

1. The combination with a motor vehicle window and door of a housing secured to the door,

an operating shaft rotatably mounted in the housing, a disk hub formed integral with the shaft, a split sleeve integral with the hub comprising two companion arcuate sections, one of the sections being provided with a notch, a cylindrical barrel received between the sleeve sections provided at diametrically opposite points with longitudinal ribs received in the space between the arcuate sections, an operating lever connected to the barrel and to the window for raising or lowering the window when the barrel is turned axially, a spring pressed dog carried by the barrel, ratchet teeth formed on the inner periphery of the housing engaged by the dog, said dog having spaced shoulders, said notch being adapted to receive said dog and permit the portions id of the an operating shaft adjacent end of the companion sleeve section passing over the shoulders to depress the dog and subsequently engage against one of said ribs of the barrel to rotate the barrel for lowering the window, a spring for returning the dog to normal position after each actuation of the barrel, and a helical spring secured stationary intermediate its ends adjacent to the housing and having its opposite ends engaging the lever on opposite sides of the pivot of the lever to counterbalance the weight of the window pane.
